CAN NOT FIND SCRIPT ENGINE "VBSCRIPT" FOR SCRIPT ... MESSAGE ON LOGON

Recently I have observed the subject problem in one of the Windows XP Pro SP-I PC. This annoying message popped up on every logon quoting some script name. The reason behind was a corrupted or missing DLL file possibly by a malicious activity which was healed by an Antivirus.

How to fix it?
An extensive search in Google gave me many outputs. The one which worked for me was the following one.
Start Menu > Run
Type the following in the Run field...
regsvr32 %systemroot%\system32\vbscript.dll
Press enter. You will get a positive confirmation message "DllRegisterserver in C:\windows\system32\vbscript.dll is succeeded"
And the problem is killed.

Another way of doing this is by editing the registry.
I assume that you know the basic registry editing functions and precautions. If not, take the guidance of an expert friend or ask me for more details.

Startmenu > Run > regedit
Enter

Navigate to HKEY_CLASSES_ROOT > CLSID > {B54F3741-5B07-11Cf-A4B0-00AA00A55E8}> InprocServer32
On the right side pane change the value of Default Key to C:\WINDOWS\system32\vbscript.dll (provided your Windows is in C Drive.)

Close the Registry Editor and Restart your PC.

That's all.
